1. IMPORTANT NOTICEthis manual contains important safety information and precautionary measures. it is impossible to list all potential hazards associated with every dust collection system in each application. Proper use of the equipment should be discussed with united air Specialists, inc. (uaS) or your local uaS representative. operating personnel should be aware of, and adhere to, the most stringent safety procedures.

EXPLOSION HAZARD• Avoid mixing combustible materials such as aluminum,

paper, wood or other organic dusts with dusts generated from grinding materials. a fire hazard could develop from sparks entering the dust collector. When collecting flammable or explosive materials, the dust collector should be located outdoors and incorporate the appropriate safety measures and/or accessories.

• When collecting emissions from spark-producing processes, care must be taken to reduce any potential fire hazards. System design should include methods to prevent sparks from entering the dust collector. Dust collectors do not contain fire extinguishing equipment unless specifically ordered. experts in the field of fire extinguishing equipment should be consulted for recommendations concerning proper fire detection and suppression systems.

• Some dust collection systems require explosion venting. consult your insurance underwriter, nfPa (national fire Protection association) manual and your local fire authorities to determine the requirements for explosion venting.

• Be careful and conscientious – consult national and local fire codes, waste disposal, safety and other appropriate authorities. comply with their recommendations for the proper installation and operation of dust collection equipment.

• Your dust collector was selected for a particular application. consult uaS prior to making any application or system changes.

• All explosion vent installations should be located to allow full-unrestricted discharge when system pressure exceeds the set pressure of the explosion vent. an explosion vent should never be located where the discharge from the vent will impact people or plant equipment.

• Do not use the explosion vent as temporary work surface for hand tools; i.e., wrenches, screw drivers, etc. Such actions can cause premature failure to occur via over stressing the explosion vent.

• All dust collectors handling hazardous or fire/explosion risk dust, as determined by the user, are recommended to be located outside the building in non-traffic areas even though the dust collector is equipped with an explosion vent.

2. INTRODUCTIONthank you for selecting uaS dust collection equipment to assist you in your commitment to a clean and safe environment. We trust that in purchasing our product, you have recognized our commitment to continually offer air cleaning equipment engineered to each dust collection need and manufactured to the highest standards. if at any time you have a question about dust collection, please do not hesitate to call your local uaS representative. the Sfc is designed to collect process generated dusts. the optimized pulse cleaning system coupled with the QuickSeal filter access doors provide the most dependable and maintenance friendly cartridge collector in the market.the Sfc dust collector should not be used for any purpose not listed in this manual.as you review this manual, refer to figure 1 for assistance in identifying dust collector parts. the Sfc Specification table in Section 3 provides additional unit information.

2.1 UNIT NOMENCLATUREExample: SFC8-2-H55Sfc = Model collector8 = number of cartridge filters2 = number of filter tiersH55 = unit base arrangement

H55 - hopper with 44” (112 cm) clearance for standard 55 gallon (208 liter) drum SD - hopper with 28” (66 cm) clearance for uaS-supplied 20 gallon (76 liter) drum oB - open bottom construction BV - custom bin vent unit with open bottom DD - dust drawer

2.2 DESCRIPTION AND OPERATIONthe Sfc is a high-efficiency cartridge dust collector designed to eliminate airborne dust as it is generated. contaminants are captured at the source(s), then conveyed through ducting to the cartridge filter section (dirty air section) where the dust is collected. clean air is then discharged from the unit through the clean air discharge.the dust collector is designed for on-line or downtime cartridge filter cleaning by means of a customer-supplied compressed air system.the Sfc is a high-efficiency, horizontally-oriented cartridge dust collector equipped with 9.48” i.D. and 13.87” o.D. cartridge filters. the larger diameter Protura® nanofiber cartridge filter design allows for lower pressure losses through the dust collector while increasing the amount of media contained in each filter. Sfc Series dust collectors have pre-engineered backward-inclined or radial-type optional blower packages in 2, 3, 5, 7-1/2, 10, 15, 20, 25 and 30 hp (1.5, 2.2, 3.7, 5.5, 7.5, 11, 15, 18.8, 22.6 kW) assemblies.there are two primary modes of operation — the air filtering operation and filter cleaning cycle. Both modes of operation are shown in figure 1.

2.3 AIR FILTERING OPERATIONthe contaminated airstream is drawn into the dust collector where its velocity is reduced by inlet baffle plates to provide even air distribution across the entire surface area of the cartridge filters. this design enhances filtration efficiency by establishing a uniform “dust cake” on the filters. the airstream is then directed around the cartridge filters and down toward the hopper, where the heavier particles discharge to the dust storage drum.the contaminated air then passes through the cartridge filters. the filter media strips the dust from the airstream, allowing only clean air to pass through the cartridge filter. the air then passes into the clean air plenum, through a blower package and is discharged from the unit.

2.4 FILTER CLEANING CYCLEDuring normal operation, the surface of the cartridge filters become loaded with contaminants. the reverse-pulse cleaning mechanism provides brief bursts of

compressed air, directed through the diaphragm valves, toward the cartridge filter. this pulsing action dislodges the collected particles from the media, where they fall into the hopper and are discharged to a dust storage drum or drawer.During the cleaning cycle, each pair of cartridge filters is cleaned individually. the solid-state sequential timer actuates a solenoid valve, which allows an air diaphragm valve to open for approximately 100 milliseconds. High-pressure air from the air manifold reservoir is directed through the diaphragm valve toward the venturi mounted on the tubesheet in front of the cartridge filters. the venturi, in conjunction with the Dif nozzle, maximizes the compressed air energy to maximize the amount of collected dust released from the filter surface.the dislodged dust removed from the filter is swept downward into the hopper. the remaining filters are cleaned sequentially. the sequencing is factory preset at 10-second intervals and is adjustable to adapt to your particular cleaning needs.

options are also possible. Structural calculations for the foundation or other mounting arrangements must include the weight of the collected material and the weight of all auxiliary equipment installed with the dust collector (ducting, abrasive inlet, blower package, afterfilter assembly, etc.). these weights must be considered together with wind loading, seismic loading and other live load ratings when designing the dust collector foundation support structure. consult a professional engineer when designing the foundation for the unit.

the system should be designed with the ability to regulate airflow. two common ways to do this are through the use of flow/volume control dampers or variable frequency drives to control the speed of the fan motor. uaS offers both of these options. if flow control dampers are selected, the interconnecting duct work should be designed to account for the installation of said damper. these dampers can be installed on the inlet or outlet ducting of the Sfc unit. Whether you control the flow through the use of a damper or VfD, the ductwork must be properly sized to meet the recommended air velocities for the material being collected.

follow ducting design methods as listed in the Industrial Ventilation Manual as recommended by the american conference of Governmental industrial Hygienists.

3.3 ASSEMBLY OF STANDARD EQUIPMENT

CRUSH AND ELECTROCUTION HAZARD use adequate safety measures when lifting and

assembling any heavy components. consult your plant safety personnel for recommendations.

in preparing to attach the filter module to the hopper, connect lifting slings and spreader bars to all filter module lifting lugs with clevis pins. use spreader bars to distribute the load evenly. Location must be clear of all obstructions, such as utility lines or roof overhangs.

remove all crating, strapping and hold-down bolts. Locate all hardware bags, sealant and other assembly materials provided with your unit.

3.3.1 HOPPER ASSEMBLIESthe Sfc Series filter module is designed to mount directly on top of the hopper assembly. a hopper assembly consists of a hopper bin, legs, side diagonal sway braces, rear diagonal sway braces and the hardware installation kit. Hopper assemblies will be shipped in pieces and will need to be assembled at the site.

the hopper sections are shipped in pieces for field assembly. Position the legs as shown in figure 4 for single module hopper assembly, or figure 5 for multi-modular hopper assemblies.

3. INSTALLATION3.1 OFF LOADING AND INSPECTION

Sfc dust collector modules are shipped assembled (with cartridges installed) on skid(s). other skids will contain the hopper/leg assembly and other components. other accessories (afterfilter assemblies, blower packages, dust storage drums, silencers, etc.) may be on additional, separate skids.

TIP OVER HAZARD Lift the dust collector components by the packing skids

or use the external lifting lugs provided on the filter module. Do not lift the filter module of the dust collector by placing lift truck forks through the cartridge filter access doors. the filter support rails or venturi installed on the tubesheet could be damaged.

upon receipt of your unit, check for any shipping damage. a damaged carton indicates that the equipment may have received rough handling during shipping that may have caused possible internal damage. notify your delivery carrier and enter a claim if any damage is found.

3.2 INSTALLATION PLANNINGthe proper location of your dust collection equipment is very important. refer to figures 2 and 3 for typical installation details.

certain items should be considered when locating the unit, such as emptying of the dust storage drum(s), filter removal requirements, compressed air connections, access to the clean air plenum, electrical connections, blower location and discharge direction. the shortest duct length with a minimum number of elbows will maximize the performance of the unit. ease of maintenance should also be considered when selecting the location and orientation of the system. refer to figure 3 for recommended clearances.

EXPLOSION HAZARD in the case of spark producing processes, system

design should incorporate measures to prevent live sparks from entering the dust collector. consult local authorities for the location of the unit and any additional precautions to consider when collecting combustible, explosive or hazardous dusts. General warnings and cautions are provided on page iii and in Section 1.

TIP OVER HAZARDthe Sfc dust collector should be mounted on a solid, level, reinforced concrete foundation. other mounting

bolts) are properly tightened before proceeding with the remainder of the installation.

install all cartridge filters removed at the beginning of the installation process and install the filter access doors (refer to Section 5.1).

3.4 ELECTRICAL INSTALLATION

ELECTRICAL SHOCK HAZARD all electrical work should be performed by a

qualified electrician in accordance with local electrical codes. Disconnect electrical power before installing or servicing any electrical component.

GENERALSeveral types of standard electrical components can be installed to control and monitor your dust collector. a VfD or a motor starter circuit (combination starter panel) is required to safely start and stop the system. a properly sized circuit breaker or fused disconnect is also required to safely work on and service the electrical system. in addition, a 115/1/60 (2 amp) control circuit is required for the pulse control panel. Some or all of the above items may be included in the controls package you purchased from uaS. any one of the following control combinations can be used:• Motor starter with Digital Pulse Monitor (DPM) for

continuous pulse cleaning.• Motor starter with Digital Pulse Control (DPC) for

on-demand pulse cleaning.• VFD with DPM for continuous pulse cleaning.• VFD with DPC for on-demand pulse cleaning.

refer to uaS sales order to verify the control configuration purchased with your unit and whether additional items are required to control and operate your system.

3.4.1 MOUNTING THE CONTROLSMount the VfD or combination starter panel for the fan motor in a convenient location. it is recommended that these controls be mounted on a wall or pedestal in an area subject to minimal vibration and electrical noise. Mounting hardware is provided by the customer or the contractor. if the panel includes the DPM or the DPc gauge and uaS timer control board, then the location of the panel must within close proximity of the dust collection unit as shown in figure 8. for additional setup and installation information refer to the VfD and/or DPM/DPc owner’s Manuals provided.

avoid mounting the panel on the collector due to vibration generated from blower assembly and the pulsing system.

for all pulse control panels, connect the black plastic pressure tubing (25’ [7.5 meters] provided by uaS) to the panel fittings and the Sfc unit. connect the dirty air plenum of the Sfc to the high pressure port (dirty air) on the panel as shown in figure 8. connect the clean air plenum of the Sfc to the low pressure port (clean air) on the panel.

3.4.2 SOLENOID VALVE ENCLOSURE WIRING

the solenoid valves at the dust collector must be wired correctly to the pulse control panel. refer to figure 9 when making connections from the pulse control panel to the solenoid valve enclosure(s).

Example: figure 9 shows the Sfc having ten valve locations per module. this means when the system pulses, “1” is the first pulse in the sequence, “2” is the second, “3” is the third, etc.

When multiple dust collector modules are installed, daisy chain the wiring so that each solenoid valve with the same module location will pulse at the same time. this means all #1 solenoid valves are connected together and wired to pulse control panel “out 1,” #2 solenoid valves are connected together and wired to pulse control panel “out 2,” etc. refer to figure 9 for the Sfc dust collector solenoid valve wiring information. When cleaning, the pulse valves sequence left to right, top to bottom.

unless specified on the uaS sales order, the customer will supply interconnecting material (conduit, wiring, etc.) from the pulse control panel to the Sfc.

3.4.3 HEATER WIRINGin cold or damp environments, the heater serves to prevent the electric solenoid valves from freezing due to cold temperatures or condensation. if optional solenoid valve heater is purchased, each 4 solenoid valve enclosures will contain a 70-watt cartridge heater, 6, 8 and 10 solenoid valve enclosures will contain a 120-watt cartridge heater internally prewired to a thermostat.

the customer must provide a 100-130Vac, 50/60Hz, 1 amp power to the heater circuit for each module. the power must be available to the module solenoid valve enclosure(s) at all times (even when the blower is shut down) to ensure temperature regulation inside each solenoid valve enclosure is continual. When multiple module solenoid valve enclosures with heaters are installed, daisy chain the wiring so that each heater will have 100/115Vac, 50/60 Hz at all times. Make certain enough current is available to supply all heaters.

Example: if three solenoid valve enclosures are supplied with cartridge heaters, make certain the voltage supply can deliver 3 amps (1amp per heater).

3.5 COMPRESSED AIR CONNECTION

Do not allow water and/or oil from the compressed air system into the compressed air manifold reservoir. to ensure a clean, dry air supply, especially when the unit is installed outdoors, a water filter with automatic drain and a coalescing filter should be installed (refer to figure 10).

clean, dry, 90-110 PSiG (6.2-7.6 Bar) compressed air is required for the pulse cleaning system to function properly. compressed air consumption is noted on the uaS sales drawing. a shut-off valve, pressure regulator and pressure gauge should be installed close to the Sfc unit. uaS recommends dedicated oil and water removal filters be used to ensure clean, dry air is delivered to the pulse system. contact your local Sfc representative for information about uaS’ Pneumatic Valve assembly. refer to figure 10 for recommended compressed air piping and table 1 below for proper compressed air line sizing.

NOTE: using table 1, select the proper diameter compressed air line pipe to supply your dust collector. the final connection size is a female 1” nPt fitting on each module.

NOTE: Purge the compressed air line to remove any debris prior to making the final connection to the Sfc compressed air manifold(s). apply pipe fitting sealant on all compressed air supply pipe fittings and connections.

3.6 ASSEMBLY OF OPTIONAL EQUIPMENT

3.6.1 BLOWER PACKAGE INSTALLATION

TIP OVER HAZARD anchor dust collector to concrete pad prior to

installing blower assembly. Make certain all hardware is properly tightened.

if a top-mount blower package was ordered, read the manufacturer’s Installation and Operation Manual completely before installing the blower. the blower Installation and Operation Manual is attached to the fan package. Perform all pre-installation checks prior to installing the blower.

TIP OVER HAZARD if blower package has a 20 HP (15 kW) motor or

larger, ensure the blower support legs are installed beneath the clean air plenum of the module to which the blower will be mounted.

for top-mount blower packages of 20 HP (15 kW) or larger, an additional set of support legs is provided. the additional support legs must be mounted under the filter module supporting the blower package (refer to figure 11). Bolt the mounting plate to the bottom of the appropriate clean air plenum with the hardware provided. Bolt the leg assemblies to the mounting plate with the hardware provided. Secure leg assemblies to the concrete mounting pad with appropriate anchoring hardware.

remove the clean air plenum cover plate on top of the filter module and save the mounting hardware. ensure ribbon gasket remains on the unit. Lift blower package using safe, suitable means and position blower base holes over filter module holes with blower discharge pointing in the desired direction. Secure with bolt/washer assemblies previously removed. top-mount blower packages include a blower outlet damper. install blower damper to outlet of blower assembly with hardware provided.

if the blower package is a ground-mount blower, read the manufacturer’s Installation and Operation Manual completely before installing the blower. the blower Installation and Operation Manual is attached to the fan package. Perform all pre-installation checks prior to installing the blower.

outlet ducting from the Sfc unit to the blower package can be connected to either the top or bottom clean air section access panel(s). it is recommended industry practice to provide vibration isolation between the blower inlet and the dust collector outlet ducting.

3.6.8 EXPLOSION VENT INSTALLATION

3.6.8.1 INTRODUCTION

your united air Specialists, inc. Dust-Hog® supplied with an explosion vent is designed to minimize structural damage in the event of an explosion. it does not prevent explosions!the responsible user should:1. take every possible precaution to prevent a fire or

explosion from occurring2. consult with their insurance carrier or local

authorities regarding the hazardous nature of dust produced by them.

3. consult and comply with national and local codes or bulletins when determining location and operation of the dust collector.

4. Do not exceed negative operating pressure of the unit.

5. Do not exceed operating temperature of the dust collector (not to exceed 180°f (82°c)).

3.6.8.2 OPERATING & PRECAUTIONS1. install unit with the explosion vent directed away

from occupied areas.2. When the explosion vent is properly installed, the

rating tag and caution stickers should be in plain sight for all to see. if the explosion vent is installed incorrectly, damage could occur to the explosion vent and to the operator or plant equipment.

3. Ductwork added to the explosion vent flange may create a secondary hazard. user must comply with nfPa standard 68, and/or other codes that apply.

4. Do not place hands or any other objects in vent opening. Serious injury or damage to plant equipment could occur.

5. if any leakage occurs, shut down unit and contact uaS immediately.

6. never inspect explosion vent(s) with unit running.7. only use explosion vent supplied by united air

Specialists, inc.8. any vent installed, which has been provided by

someone other than uaS will void all warranties on the dust-collector.

in case of explosion, contact uaS immediately. Do not operate or rearm the collector with another explosion vent without contacting united air Specialists inc. first. Serious injury could occur.

3.6.8.3 UNIT SET-UPthe normal shipping routine for an assembled Sfc unit is with an enclosed box truck. this type of truck will not be able to transport an assembled 4-high unit due to height restrictions within the vehicle. When shipping this unit, it will be necessary to ship the top panel and explosion vent separately. this will require the customer to assemble this to the unit on site. refer to figure 14 for assembly details.

3.6.9 EXTENDED DIRTY AIR PLENUM (EDAP) FOR 5 HIGH SFC UNIT

the normal shipping routine for an assembled Sfc unit is with an enclosed box truck. this type of truck will not be able to transport an assembled 5-high unit due to height restrictions within the vehicle. When shipping this unit, it will be necessary to ship the eDaP separately. this will require the customer to assemble this to the unit on site. refer to figures 15 & 16 for assembly details.

4. OPERATION

Shut off unit disconnect and lock out all electrical power to the dust collector prior to performing service work.

Prior to unit start-up, all installation set-up instructions must be completed as specified by this manual. refer to Section 4.

4.1 START-UPinspect the installation area and make certain no tools, parts, etc., have been left on or inside the Sfc unit. check blower discharge to make certain it is free from all debris.

Start motor/blower and check for proper rotation. a rotation arrow is located on the blower housing. all top-mount blower assemblies rotate in a clockwise rotation as viewed from the driven end (motor end with motor cooling fan). if blower is rotating in the opposite direction, place disconnect switch in the off position to the motor starter. for 3-phase blowers, interchange any two power wires to the motor at the load side of the motor starter contactor. for single-phase power, refer to motor nameplate for which two wires to interchange at motor junction box. engage starter disconnect switch, start blower and recheck rotation.

NOTE: Proper blower rotation is required to move the designed amount of air. a blower rotating in the incorrect direction will only move approximately 40% of design airflow.

CAUTION the blower assembly provided by uaS includes

an outlet damper. if the blower assembly was purchased separately, ensure an outlet damper is included. close the blower discharge damper to the 50% open position and tighten in place. if a volume control damper is provided in another part of the dust collection system, adjust second damper to the 50% open position and tighten in place.

NOTE: it is important that the air volume of the dust collection system is at design conditions at system start-up. there is a minimal pressure differential across new cartridge filters. if the volume control damper is not correctly adjusted, the air volume will be above design conditions for airflow and will affect cartridge filter life and may kick-out starter overloads.

Verify dust collector system airflow is adjusted to design conditions with a new, clean filter using the volume control dampers installed in the system. failure to properly adjust system airflow will affect cartridge filter life.

the air volume should be adjusted based on the performance of the entire system. the air volume control damper must be adjusted to the system design airflow. closing the volume control damper decreases system airflow. opening the volume control damper increases system airflow.

turn on the compressed air supply to the dust collector air manifold reservoir. adjust the pressure regulator until the gauge reads 90-110 PSiG (6.2-7.6 Bar).

4.2 CHECKLISTcheck the discharge of the blower assembly. initially, some dust may discharge from the blower assembly as the filters are being seasoned. this may last several minutes after which the discharge air should remain visibly clean.

Measure the total airflow and static pressure at the inlet to the Sfc unit. adjust the blower damper for the desired airflow. check to ensure that adequate air is being drawn into each of the collection points of the system. adjust the individual dampers for each operation to balance the system airflow. recheck the total system airflow and adjust the blower damper to desired system airflow. this procedure may need to be repeated several times until the entire system is within system design airflow specifications.

check the differential pressure reading across the dust collector clean-to-dirty air sections. a normal differential pressure drop reading is between 1”-5” w.g. (25-127 mmaq). at start-up, this reading is generally in the 1”-3” w.g. (25-76 mmaq) range. Please list the reading here for future reference.

initial dust collector differential pressure reading across filters is ____________” w.g. or ____________ (mmaq) on _____________ (date).

4.3 CHECKING THE PULSE CLEANING SYSTEM

confirm the type of pulse cleaning controller delivered with your system. your system was delivered with one of the following:• DPM Pulse Control Panel• DPC Pulse Monitor Panelcheck the pulse cleaning system for proper operation. the compressed air pressure should be between 90-110 PSiG (6.2-7.6 Bar). uaS’ pulse control panels are factory set to pulse every 10 seconds. refer to the DPM/DPc Installation and Operation Manual specified with the dust collector to change these initial settings. check to ensure the pulse (diaphragm) valves are “firing” at approximately 10-second intervals and deliver a crisp sounding pulse to each filter. the valves should not deliver a weak sound. if an extended “hiss” is heard afterwards, the pulse is too long, which does not assist in cleaning, and wastes compressed air.• If your system is supplied with a DPM Pulse

Monitor Panel, place the “continuous clean/PS” switch on the timerboard to the “continuous clean” position. or if the system is supplied with DPc Pulse control, place the “continuous clean/PS” switch on the timerboard to PS position. the Mot auX terminals at the timerboard should be field wired for the pulsing to become active. to activate, energize the motor starter to close the isolated auxiliary contact wired to the timerboard Mot auX terminals. Verify consistent firing of each solenoid valve exhaust port.

NOTE: it is important that the compressed air pressure is in the 90-110 PSiG range (6.2-7.6 Bar) immediately prior to pulse. if the delivery capability of your compressed air source cannot return the manifold pressure to above 90 PSiG during the “Pulse Delay” (factory set at 10 sec.) interval, adjust the pulse delay at the timerboard and monitor the pressure. a longer interval will raise the operating pressure, which is the pulse delay. (adjust from position 2 to position 3 on the timer board.) allow sufficient time for the system to stabilize after each adjustment before making any further adjustment. adjust until the desired manifold pressure is reached.

4.3.1 DIGITAL PULSE MONITOR (DPM) PANEL

the DPM is always set to “continuous clean” pulse mode, which means pulse cleaning is operating continuously when the system is online. refer to the DPM/DPc Installation and Operation Manual for additional information.

CAUTION

24


4.3.2 DIGITAL PULSE CONTROL (DPC) PANEL

the DPc Pulse control Panel is set for “Pressure Switch” or “PS” pulse mode. With the DPc control, the desired pressure can be maintained by adjusting the high and low set-points on the panel. the factory setting is 3.0 (high set-point) and 2.5 (low set-point). this allows a 0.5” “deadband” and the pulse system will maintain the desired pressure. the high and low set-points on the DPc can be adjusted as the filters season and continuous pulsing occurs. adjust upward in 0.5” increments until pulsing stops. continue adjustments, when required, until the high set-point reaches 5”. no further adjustments should be made over 5” w.g.

5. SERVICE

Before servicing dust collector:

• Wear appropriate protective clothing when servicing dust collector.

• Disconnect and lockout electrical power to the unit and control panel.

• Close off and slowly bleed the compressed air supply from the air manifold reservoir. air manifold reservoir pressure should be reduced to 0 PSiG (0 Bar).

• Collected dust may be hazardous. Consult proper authorities for handling and disposal.

• Collected dust may be a potential fire hazard. Welding, grinding or operations involving open flames should not be performed without fire protection measures in place. refer to Section 1 of this manual for additional precautions.

• Disposal of collected dust must be according to federal, state and local regulations and all appropriate authorities.

5.1 CARTRIDGE FILTER REMOVAL AND REPLACEMENT

Protura® nanofiber filters are the only replacement filters which provide the highest level of performance expected from the Sfc Dust collector.replacement cartridge filters should be ordered when the differential pressure is consistently above 5” w.g. (127 mmaq) or system airflow is inadequate and won’t significantly recover with off-line (no fan pulse) cleaning. to order filters, contact uaS at 888-515-8800.

TO REPLACE CARTRIDGE FILTERS1. read and follow caution instructions in box above

before servicing your unit. Start with the top row of QuickSeal doors. (figure 17)

2. tap the metal surface of each filter access door to remove collected particles from the inner door gasket. Pull the QuickSeal door handle away from the dust collector until the handle makes a 90° angle with the door cover. the filter access door is now in an unlatched position. Lift the QuickSeal filter access door upward until the door rods clear the side support brackets. Pull the door away from the dust collector. tilt the door cover away from the dust collector once free from the support brackets to trap any dust on the inside of the filter access door. Dispose of dust into a suitable container. Place filter access door in a safe place.

3. Move filter from side to side to break the gasket seal between filter-to-filter-to-tubesheet locations. rotate the filter 180° to allow the dust on top of the cartridge filter to fall into the dust collector hopper.

4. Slide the filters out of the dust collector and transfer to a suitable disposal container. repeat this procedure for the remaining filters.

5. inspect the tubesheet and make certain the gasket sealing area is free of dust to ensure proper sealing of the new filter. Make certain the area is dry after the cleaning process is complete.

6. install new Protura® nanofiber cartridges into each filter compartment, gasket end first. clean the filter door gaskets and align with door rod support brackets on the dust collector. Door handle must be placed at a 90° angle to filter access door prior to placing the door cover plate support rod in the support brackets (refer to figure 17). the flat surface of the door handle should be facing downward. to close the filter access door, push the door handle upward, toward the unit.

the QuickSeal filter access door handle must be in a perpendicular orientation to door surface prior to being closed. a flat solid section of door handle will be visible when door assembly is in the properly closed position. refer to figure 17.

if cam surface of the door handle is visible, QuickSeal filter door assembly has been improperly installed.

7. the Sfc dust collector is now ready to be placed back in service. reconnect electrical power and air supply. Please follow the initial start-up checklist to ensure proper unit performance.

5.2 DUST REMOVAL

Do not let the dust storage drum overfill. this can cause poor dust collector performance and require extensive clean-up due to the overflow of dust when removing the collection container(s).

turn off the dust collector (power to fan system and compressed air to cleaning system) and empty the dust storage drum as necessary to prevent dust from accumulating in the hopper(s). empty the dust storage drum(s) when two-thirds full. if the hopper has a slide gate, close the slide gate before servicing the dust storage drum(s). the dust collector fan and compressed air cleaning systems do not have to be turned off if the hopper slide gate is closed prior to servicing storage drums. remember to open the slide gate when the dust storage drum is replaced.

5.3 SERVICING THE COMPRESSED AIR COMPONENTS

Shut off and slowly release the pressure in the compressed air piping or the Sfc compressed air manifold reservoir prior to servicing this equipment.

1. the compressed air system should be periodically checked to ensure clean, dry, oil-free air is delivered to the Sfc dust collector. check the compressed air components and service as recommended by the manufacturer.

2. Periodically check the dust collector air manifold reservoir(s) for contaminants and drain any condensed liquid from manifold reservoirs.

3. With the compressed air supply turned on, check the diaphragm valves, electronic solenoid valves and interconnecting tubing between both devices for any air leakage. replace any components that are defective or worn.

5.4 SERVICING THE DIRECT DRIVE BLOWER AND MOTOR SYSTEM

ELECTRIC SHOCK HAZARD all electrical work should be performed by a qualified

electrician in accordance with local electrical codes. Disconnect electrical power before installing or servicing any electrical component.

refer to blower assembly Installation and Operation Manual provided with blower assembly for servicing requirements.

5.5 SERVICING CARTRIDGE MEDIABefore replacing cartridges, try down time (fan off) to see if system recovers. if upon restart, collector S.P. is 2-1/2” (63 mmaq) to 3” (76 mmaq) and it takes several days to work back up to over 5” (127 mmaq), there is still “life” left in the cartridges. if upon restart, 4 hours later S.P. is back over 5” (127 mmaq), it is time to change out the cartridges.
